7L27/38

Designed for efficient and reliable propulsion in marine applications, the MAN 7L27/38 is a robust four-stroke engine that ensures consistent performance across various load ranges. This engine is known for its quick acceleration and immediate load response, making it an ideal choice for vessels requiring high operational flexibility. The MAN 7L27/38 boasts a proven track record of reliability, with long times between overhauls and minimal unscheduled maintenance, reducing downtime and operational costs. With a cylinder bore of 270 mm and a stroke of 380 mm, the engine offers a swept volume per cylinder of 21.76 dm³. It is available in configurations with 6, 7, 8, or 9 cylinders, providing a range of power outputs to suit different vessel sizes and requirements. The MAN 7L27/38 operates at a speed of 800 rpm, delivering a maximum continuous rating (MCR) of 2,380 kW for the 7-cylinder version. The engine is equipped with a high-efficiency constant pressure turbocharging system from the MAN TCR series, enhancing performance and efficiency. It also features an in-house developed safety and control system, MAN SaCoS one, ensuring reliable operation under all conditions. The fuel system includes both conventional main injection and a variable injection system for optimal fuel consumption while meeting IMO Tier II emission standards. For even stricter compliance, the engine can be configured to meet IMO Tier III regulations with the addition of a selective catalytic reduction (SCR) system. The MAN 7L27/38 is designed with a "pipeless" concept, integrating cooling water and lube oil pumps along with thermostatic valves in the front-end box. This design simplifies maintenance and reduces the risk of leaks. The engine also offers a power-to-weight ratio of 12.0 to 13.24 kg/kW, making it a highly efficient choice for marine propulsion systems.
